The answer to this math problem is = 0
Answer:
45 feet
Step-by-step explanation:
Use ratios:
x = 540 inches
divide by 12 to get 45 feet
Step-by-step explanation:
Take the number as x
12x-40=7x+25
collect like terms
12x-7x=25+40
5x=65(divide both sides by 5)
x=13
Therefore number is 13
2X^2+4X-8-X^2+6X-4
X^2+4X-8+6X-4
X^2+10X-12
Answer: y= -4x+9 or 4x+y=9
Step-by-step explanation: 4x+y+-10 is in standard form. To move it to an easier to work with form you move the 4x over using subtraction. This form is called slope intercept form. The slope intercept form of the given equation is y=-4x-10. This gives you the slope, which is 4. Then you add the slope and the point needed to find the parallel line of and make it point slope form. In this case it is y-5=-4(x-1). When you simplify it you get y= -4x+9. If you need the answer in standard form it is 4x+y=9
